a low-temperature hydrothermal vein mineral in metamorphosed limestones and chlorite schists;fire-proof material
1)Magnesium hydroxide is common component of antacids and laxatives ; it interferes with the absorption of folic acid and iron. Magnesium hydroxide has low solubility in water; all of magnesium hydroxide that does dissolve does dissociate. Since the dissociation of this small amount of dissolved magnesium hydroxide is complete, magnesium hydroxide is considered a strong base.
2)Non-halogenated.Excellent performance on flame retardancy and smoke abatement.
3)Low toxicity, no smell and noncorrosive, good heat stablity, decomposition temperature at 330, especially suitable for resin processed in relative high temperature. fire-proof material
